G93.1 vs O89.2
G93.1 (Anoxic brain damage, not elsewhere classified) compared with O89.2 (Central nervous system complications of anesthesia during the puerperium), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. G93.1 carries an Excludes1 note covering O89.2: “cerebral anoxia due to anesthesia during the puerperium (O89.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
